“…The old model of angel deals is alive and well. Angels love to share deals with each other. It is how angel rounds come together. But AngelList adds at least two things to the mix. First, it adds a place where the deals can come together online. And second it adds people to the mix that would not be part of the offline deal sharing networks that already exist.

“I am on AngelList. I see all the deals come together. I don’t personally invest in angel deals in the web/tech space because of potential conflict with USV down the road. But even so, I find it immensely useful to see what companies are getting traction in the angel market. It’s part of my radar/early warning system. And it is entirely possible that we will decide that USV needs to participate in an angel round that is coming together on AngelList, although that has not yet happened.

“So if you are putting together an angel round, particularly if you already have it partially raised but need to finish it off, I strongly suggest looking into AngelList. It’s a great service.”

Fred describes our value proposition better than we do. It’s not just great PR when your users blog and tweet about you — it’s also a form of customer development.
